Plz Help!!!! Radio questions

Sup everybody. I havent been on in a while because ive been at skool. But i have saved up 300 bucks and i want to upgrade my radio. Now i know that the stock radio is pretty good but i would like a dvd touchscreen head unit.

Ive been searching on soniceletronix.com looking at some and i cant afford a pioneer radio but i have seen some thats made by a brand called Pyle. Is this a good unit to buy how do they sound????? Is it worth it?????

And if you have any suggestions i would be greatly appreciative towards your remarks. I just want a good unit without burning the pocket too much. Thanks guys and here are the links for the two radios. Thanks again
